Overview

These injectors provide 30% more flow over stock LT4 injectors, supplying the necessary fuel for high-horsepower applications. They utilize the same nozzle designed by GM and feature internal modifications while retaining the original coil and ECU programming. Proper tuning is required after installation to ensure correct air/fuel ratios.
Show original supplier description
The Fuel Injector Connection FICGDI is a set of eight high-flow, direct-injection fuel injectors specifically engineered for Gen V LT series engines, including applications for the 2016-2024 Camaro SS & ZL1, 2014-2019 Corvette, and 2014-2018 Silverado & GMC Sierra 1500 with 5.3L & 6.2L engines. These injectors offer a 30% increase in fuel flow compared to stock LT4 injectors. This enhanced flow capability is crucial for supporting high-horsepower builds, eliminating the need for auxiliary fuel systems. The FICGDI injectors leverage the same GM-designed nozzle for optimal performance and compatibility, with all modifications made internally to preserve the original coil and ECU characteristics. Installation of these injectors necessitates proper tuning to maintain the correct air/fuel ratio and ensure optimal engine operation. The product replaces factory injectors and is recommended for high-horsepower applications. Sold as a set of eight.
